"menu_order" breaks for topics with more than 1,000 replies

Description

While inserting a new reply in bbp_new_reply_handler() the 'menu_order' is defined by:

'menu_order' => bbp_get_topic_reply_count( $topic_id, false ) + 1

With $integer = false this will trigger bbp_number_format() and will return a formatted number. With more than 1,000 replies you'll get something like "1,012" which results as 'menu_order' = 2 in my database.

This leads to defect freshness links, since bbp_get_reply_position() will return wrong values.
